TECH REPORT: NEED TO WORK ON PORTAL!!!


Here is the current distribution of slides. It might change as we develop our outlines and realize maybe one persons part is a lot bigger, or if someone else knows the aspects better. Be prepared to present your outline!!!
Avani: 8, 9, 10, 18, 18, 19, 20, 23, 30, 31, 32, 33, 34, 41, 42, 43, 50

NEW POWERPOINT:


for this one, u can put in the data.. lol




i forgot about this one, I'm not sure how to describe the procedure... but here it is, theres also a graph for it but it won't open on my computer. it "tore" at 37lbs but nothing really happened to the product, it wasnt actually ripped, the machine thought it was because of the chain pulling unevenly on it or something.. idk.


i think these already had some revisions


these were the latest ones


tests with data
note for conclusions:
flex test: the different angles produced same results for different marks because the product is all one material, so the location of the mark didn't have much of an impact
water abs: the starting mass varied due to the slight difference of mass in between the products because of uneven layers, etc.
surface: all surfaces provided the same result--gum stuck to the shield; however, that does not make the product unsuccessful as it is mean to shield the sole.
heat resistance: we know rubber is supposed to melt at F, we reached temps of F because our research of common walking surfaces showed a high of __F.

just some things to throw in there.


Heat resistance test

The purpose of the heat resistance test is to make sure the product behaves the same in environments of varying temperatures that it is likely to encounter.

Materials
Tester shoe
Product
Hot plate

Procedure

1. Obtain the materials, and apply the product to the shoe.
2. Heat the hot plate to 100 degrees Fahrenheit.
3. Place the shoe on the hot plate for 3 minutes.
4. After time is up, remove the shoe from the hot plate and observe if any changes occurred to the product.
5. Repeat steps 1-4 changing the temperature in step two to 120 degrees, 140 degrees and 160 degrees.

In conclusion, for a successful product, no changes in the product should occur within the test. The temperature range accounts for asphalt or sand in the summer that are known to reach temperatures up to 140 degrees Fahrenheit.



Slip resistance test

This test is intended to test the product for safety in regards to slipperiness on different surfaces.

Materials
Tester shoe
Product
Testing pendulum
Tile surface
Grass patch
Carpet path
Pavement block

1. Apply the product to the shoe.
2. Set up the pendulum on the tile surface .
3. Apply the shoe on the bottom of the arm.
4. Set the pendulum arm up at 1 meter height.
5. Release the arm.
6. Observe if the arm is stopped at the contact with the surface.
7. Set the arm up again at 1meter height.
8. Add enough water to cover the entire surface.
9. Release the arm.
10. Observe if the arm is stopped at the contact with the surface.
11. Repeat the steps 4-10 with the different surfaces.

Data collection is based on qualitative data of whether the shoe was stopped on the surface or not. However, if it does slip, it can be observed how much the surface slowed the arm down.
